so long as you think the level is right and there's no air where there shouldn't be, can you go in diagnostics tell it to go away and see what happens... in today's world I can imaging it noticed you disconnected it and wants dealer tools to turn it off

is your tool up to date…. can't have that message without an error.... unless there a software bug and a module needs flashing with an update

Hi, did you measure the amount of coolant that you re-filled it with ? if not the cooling system may not actually be full they are prone to getting air locked when they have been completely drained.

I had that message a while back, coolant sensor in bottle was faulty. EDIT. Sorry just remembered it might have been coolant level message?
